A security vulnerability has been identified in the IBL Software Engineering Visual Weather and derived products (NAMIS, Aero Weather, Satellite Weather). The vulnerability is present in the Product Delivery Service (PDS) component in specific server configurations where the PDS pipeline utilizes the IPDS pipeline with Message Editor Output Filters enabled. A remote unauthenticated attacker can exploit this vulnerability to send unauthenticated requests to execute the IPDS pipeline with specially crafted Form Properties, enabling remote execution of arbitrary Python code. This vulnerability could lead to a full system compromise of the affected server, particularly if Visual Weather services are run under a privileged user account—contrary to the documented installation best practices. Upgrade to the patched versions 7.3.10 (or higher), 8.6.0 (or higher).
